What Is External Wall Insulation?
External Wall Insulation (EWI) is one of the most effective ways to enhance your property’s energy performance. By applying a thermal barrier to the outer walls, EWI prevents heat loss, eliminates cold spots, and protects your home from the elements. It’s especially effective for older buildings or homes without cavity walls, offering both performance and aesthetic upgrades.
With a wide range of colours and finishes available, EWI also allows homeowners to modernise their property’s look while lowering energy bills and improving internal comfort. It’s a smart, long-lasting solution to increase property value and reduce environmental impact.
